HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

While the other answers are great and answer the question there is one thing to consider when using input type="submit" and button. With an input type="submit" you cannot use a CSS pseudo element on the input but you can for a button!

This is one reason to use a button element over an input when it comes to styling.

A. It is not valid HTML nor XHTML

In the official W3C XHTML specification, Section B. "Element Prohibitions", states that:

"form must not contain other form elements."

http://www.w3.org/TR/xhtml1/#prohibitions

As for the older HTML 3.2 spec, the section on the FORMS element states that:

"Every form must be enclosed within a FORM element. There can be several forms in a single document, but the FORM element can't be nested."

B. The Workaround

There are workarounds using JavaScript without needing to nest form tags.

"How to create a nested form." (despite title this is not nested form tags, but a JavaScript workaround).

Answers to this StackOverflow question

Note: Although one can trick the W3C Validators to pass a page by manipulating the DOM via scripting, it's still not legal HTML. The problem with using such approaches is that the behavior of your code is now not guaranteed across browsers. (since it's not standard)

Just use

?

<form action="?" method="post" enctype="multipart/form-data" name="myForm" id="myForm">

It doesn't violate HTML5 standards.

Check out https://github.com/niclasko/Cypher.js (note: I'm the author)

It's a zero-dependency Javascript implementation of the Cypher graph database query language along with a graph database. It runs in the browser (tested with Firefox, Chrome, IE).

With relevance to the question. It can be used to query JSON endpoints:

load json from "http://url/endpoint" as l return l limit 10

Here's an example of querying a complex JSON document and performing analysis on it:

Cypher.js JSON query example

The general rule seems to be that browsers encode form responses according to the content-type of the page the form was served from. This is a guess that if the server sends us "text/xml; charset=iso-8859-1", then they expect responses back in the same format.

If you're just entering a URL in the URL bar, then the browser doesn't have a base page to work on and therefore just has to guess. So in this case it seems to be doing utf-8 all the time (since both your inputs produced three-octet form values).

The sad truth is that AFAIK there's no standard for what character set the values in a query string, or indeed any characters in the URL, should be interpreted as. At least in the case of values in the query string, there's no reason to suppose that they necessarily do correspond to characters.

It's a known problem that you have to tell your server framework which character set you expect the query string to be encoded as--- for instance, in Tomcat, you have to call request.setEncoding() (or some similar method) before you call any of the request.getParameter() methods. The dearth of documentation on this subject probably reflects the lack of awareness of the problem amongst many developers. (I regularly ask Java interviewees what the difference between a Reader and an InputStream is, and regularly get blank looks)

You shouldn't have to care that much. RFC 3339, according to itself, is a set of standards derived from ISO 8601. There's quite a few minute differences though, and they're all outlined in RFC 3339. I could go through them all here, but you'd probably do better just reading the document for yourself in the event you're worried:

http://tools.ietf.org/html/rfc3339

Well you don't really have to worry about IE7 code not working in IE8 because IE8 has compatibility mode (it can render pages the same as IE7). But if you still want to target different versions of IE, a way that's been done for a while now is to either use conditional comments or begin your css rule with a * to target IE7 and below. Or you could pay attention to user agent on the servers and dish up a different CSS file based on that information.

If you can use javascript and strictly require it on your web, you can put textboxes, checkboxes and whatever on each row of your table and at the end of each row place button (or link of class rowSubmit) "save". Without any FORM tag. Form than will be simulated by JS and Ajax like this:

<script type="text/javascript">
$(document).ready(function(){
  $(".rowSubmit").click(function()
  {
     var form = '<form><table><tr>' + $(this).closest('tr').html() + '</tr></table></form>';
     var serialized = $(form).serialize(); 
     $.get('url2action', serialized, function(data){
       // ... can be empty
     }); 
   });
});        
</script>

What do you think?

PS: If you write in jQuery this:

$("valid HTML string")
$(variableWithValidHtmlString)

It will be turned into jQuery object and you can work with it as you are used to in jQuery.

It breaks semantics, that's all. It works fine, but there may be screen readers or something down the road that won't enjoy processing your HTML if you "break semantics".

I try to avoid TABLEs as much as possible, but when we are designing complex forms that mix multiple control types and different caption positions with pretty strict controls on grouping, using DIVs is unreliable or often near impossible.

Now, I will not argue that these forms could not be redesigned to better accommodate a DIV based layout, but for some of them our customer is adamant about not changing the existing layouts from the previous version (written in classic ASP) because it parallels a paper form that their users are familiar with.

Because the presentation of the forms is dynamic (where the display of some sections is based on the state of the case or the permissions of the user), we use sets of stacked DIVs, each containing a TABLE of logically grouped form elements. Each column of the TABLE is classed so that they can be controlled by CSS. That way we can turn off different sections of the form without the problem of not being table to wrap rows in DIVs.

You can add a file as a resource using two separate methods.

The C# code required to access the file is different, depending on the method used to add the file in the first place.

Method 1: Add existing file, set property to Embedded Resource

Add the file to your project, then set the type to Embedded Resource.

NOTE: If you add the file using this method, you can use GetManifestResourceStream to access it (see answer from @dtb).

Method 2: Add file to Resources.resx

Open up the Resources.resx file, use the dropdown box to add the file, set Access Modifier to public.

NOTE: If you add the file using this method, you can use Properties.Resources to access it (see answer from @Night Walker).

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

You can also use a while loop:

while (true) {
    //your code
}

Swift 5.0

func makeTransform(horizontalDegree: CGFloat, verticalDegree: CGFloat, maxVertical: CGFloat,rotateDegree: CGFloat, maxHorizontal: CGFloat) -> CATransform3D {
    var transform = CATransform3DIdentity
           
    transform.m34 = 1 / -500
    
    let xAnchor = (horizontalDegree / (2 * maxHorizontal)) + 0.5
    let yAnchor = (verticalDegree / (-2 * maxVertical)) + 0.5
    let anchor = CGPoint(x: xAnchor, y: yAnchor)
    
    setAnchorPoint(anchorPoint: anchor, forView: self.imgView)
    let hDegree  = (CGFloat(horizontalDegree) * .pi)  / 180
    let vDegree  = (CGFloat(verticalDegree) * .pi)  / 180
    let rDegree  = (CGFloat(rotateDegree) * .pi)  / 180
    transform = CATransform3DRotate(transform, vDegree , 1, 0, 0)
    transform = CATransform3DRotate(transform, hDegree , 0, 1, 0)
    transform = CATransform3DRotate(transform, rDegree , 0, 0, 1)
    
    return transform
}

func setAnchorPoint(anchorPoint: CGPoint, forView view: UIView) {
    var newPoint = CGPoint(x: view.bounds.size.width * anchorPoint.x, y: view.bounds.size.height * anchorPoint.y)
    var oldPoint = CGPoint(x: view.bounds.size.width * view.layer.anchorPoint.x, y: view.bounds.size.height * view.layer.anchorPoint.y)
    
    newPoint = newPoint.applying(view.transform)
    oldPoint = oldPoint.applying(view.transform)
    
    var position = view.layer.position
    position.x -= oldPoint.x
    position.x += newPoint.x
    
    position.y -= oldPoint.y
    position.y += newPoint.y
    
    print("Anchor: \(anchorPoint)")
    
    view.layer.position = position
    view.layer.anchorPoint = anchorPoint
}

you only need to call the function with your degree. for example:

var transform = makeTransform(horizontalDegree: 20.0 , verticalDegree: 25.0, maxVertical: 25, rotateDegree: 20, maxHorizontal: 25)
imgView.layer.transform = transform

Executive summary: Don't do that.

j_random_hacker's answer tells you how to do this. However, I would also like to point out that you should not do this. The whole point of templates is that they can accept any compatible type, and Java style type constraints break that.

Java's type constraints are a bug not a feature. They are there because Java does type erasure on generics, so Java can't figure out how to call methods based on the value of type parameters alone.

C++ on the other hand has no such restriction. Template parameter types can be any type compatible with the operations they are used with. There doesn't have to be a common base class. This is similar to Python's "Duck Typing," but done at compile time.

A simple example showing the power of templates:

// Sum a vector of some type.
// Example:
// int total = sum({1,2,3,4,5});
template <typename T>
T sum(const vector<T>& vec) {
    T total = T();
    for (const T& x : vec) {
        total += x;
    }
    return total;
}

This sum function can sum a vector of any type that support the correct operations. It works with both primitives like int/long/float/double, and user defined numeric types that overload the += operator. Heck, you can even use this function to join strings, since they support +=.

No boxing/unboxing of primitives is necessary.

Note that it also constructs new instances of T using T(). This is trivial in C++ using implicit interfaces, but not really possible in Java with type constraints.

While C++ templates don't have explicit type constraints, they are still type safe, and will not compile with code that does not support the correct operations.

LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.

Using dummies::dummy():

library(dummies)

# example data
df1 <- data.frame(id = 1:4, year = 1991:1994)

df1 <- cbind(df1, dummy(df1$year, sep = "_"))

df1
#   id year df1_1991 df1_1992 df1_1993 df1_1994
# 1  1 1991        1        0        0        0
# 2  2 1992        0        1        0        0
# 3  3 1993        0        0        1        0
# 4  4 1994        0        0        0        1

I would assume that one might want a solution that produces a widely useable base64 URI. Please visit data:text/plain;charset=utf-8;base64,4pi44pi54pi64pi74pi84pi+4pi/ to see a demonstration (copy the data uri, open a new tab, paste the data URI into the address bar, then press enter to go to the page). Despite the fact that this URI is base64-encoded, the browser is still able to recognize the high code points and decode them properly. The minified encoder+decoder is 1058 bytes (+Gzip?589 bytes)

Below is the source code used to generate it.

var fromCharCode = String.fromCharCode;
var btoaUTF8 = (function(btoa, replacer){"use strict";
    return function(inputString, BOMit){
        return btoa((BOMit ? "\xEF\xBB\xBF" : "") + inputString.replace(

    }
})(btoa, function(nonAsciiChars){"use strict";
    // make the UTF string into a binary UTF-8 encoded string
    var point = nonAsciiChars.charCodeAt(0);

        if (nextcode !== nextcode) // NaN because string is 1 code point long
            return fromCharCode(0xef/*11101111*/, 0xbf/*10111111*/, 0xbd/*10111101*/);
        // https://mathiasbynens.be/notes/javascript-encoding#surrogate-formulae
        if (nextcode >= 0xDC00 && nextcode <= 0xDFFF) {
            point = (point - 0xD800) * 0x400 + nextcode - 0xDC00 + 0x10000;
            if (point > 0xffff)
                return fromCharCode(
                    (0x1e/*0b11110*/<<3) | (point>>>18),

                    (0x2/*0b10*/<<6) | ((point>>>6)&0x3f/*0b00111111*/),
                    (0x2/*0b10*/<<6) | (point&0x3f/*0b00111111*/)
                );
        } else return fromCharCode(0xef, 0xbf, 0xbd);
    }
    if (point <= 0x007f) return nonAsciiChars;
    else if (point <= 0x07ff) {
        return fromCharCode((0x6<<5)|(point>>>6), (0x2<<6)|(point&0x3f));
    } else return fromCharCode(

        (0x2/*0b10*/<<6) | (point&0x3f/*0b00111111*/)
    );
});

Then, to decode the base64 data, either HTTP get the data as a data URI or use the function below.

var clz32 = Math.clz32 || (function(log, LN2){"use strict";
    return function(x) {return 31 - log(x >>> 0) / LN2 | 0};
})(Math.log, Math.LN2);
var fromCharCode = String.fromCharCode;
var atobUTF8 = (function(atob, replacer){"use strict";
    return function(inputString, keepBOM){
        inputString = atob(inputString);
        if (!keepBOM && inputString.substring(0,3) === "\xEF\xBB\xBF")
            inputString = inputString.substring(3); // eradicate UTF-8 BOM
        // 0xc0 => 0b11000000; 0xff => 0b11111111; 0xc0-0xff => 0b11xxxxxx
        // 0x80 => 0b10000000; 0xbf => 0b10111111; 0x80-0xbf => 0b10xxxxxx
        return inputString.replace(/[\xc0-\xff][\x80-\xbf]*/g, replacer);
    }
})(atob, function(encoded){"use strict";
    var codePoint = encoded.charCodeAt(0) << 24;
    var leadingOnes = clz32(~codePoint);
    var endPos = 0, stringLen = encoded.length;
    var result = "";
    if (leadingOnes < 5 && stringLen >= leadingOnes) {
        codePoint = (codePoint<<leadingOnes)>>>(24+leadingOnes);
        for (endPos = 1; endPos < leadingOnes; ++endPos)
            codePoint = (codePoint<<6) | (encoded.charCodeAt(endPos)&0x3f/*0b00111111*/);
        if (codePoint <= 0xFFFF) { // BMP code point
          result += fromCharCode(codePoint);
        } else if (codePoint <= 0x10FFFF) {
          // https://mathiasbynens.be/notes/javascript-encoding#surrogate-formulae
          codePoint -= 0x10000;
          result += fromCharCode(
            (codePoint >> 10) + 0xD800,  // highSurrogate
            (codePoint & 0x3ff) + 0xDC00 // lowSurrogate
          );
        } else endPos = 0; // to fill it in with INVALIDs
    }
    for (; endPos < stringLen; ++endPos) result += "\ufffd"; // replacement character
    return result;
});

The advantage of being more standard is that this encoder and this decoder are more widely applicable because they can be used as a valid URL that displays correctly. Observe.

In addition to being very standardized, the above code snippets are also very fast. Instead of an indirect chain of succession where the data has to be converted several times between various forms (such as in Riccardo Galli's response), the above code snippet is as direct as performantly possible. It uses only one simple fast String.prototype.replace call to process the data when encoding, and only one to decode the data when decoding. Another plus is that (especially for big strings), String.prototype.replace allows the browser to automatically handle the underlying memory management of resizing the string, leading a significant performance boost especially in evergreen browsers like Chrome and Firefox that heavily optimize String.prototype.replace. Finally, the icing on the cake is that for you latin script exclusivo users, strings which don't contain any code points above 0x7f are extra fast to process because the string remains unmodified by the replacement algorithm.

I have created a github repository for this solution at https://github.com/anonyco/BestBase64EncoderDecoder/

Where's the problem

In your HTML all h2s have the same off-set of 4 columns, so they won't make a diagonal.

How to fix it

A row has 12 columns, so we should put every h2 in it's own row. You should have something like this:

<div class="jumbotron">
    <div class="container">
        <div class="row">
                <h2 class="col-md-4 col-md-offset-1">Browse.</h2>
        </div>
        <div class="row">
                <h2 class="col-md-4 col-md-offset-2">create.</h2>
        </div>
        <div class="row">
                <h2 class="col-md-4 col-md-offset-3">share.</h2>
        </div>
    </div>
</div>

An alternative is to make every h2 width plus offset sum 12 columns, so each one automatically wraps in a new line.

<div class="jumbotron">
    <div class="container">
        <div class="row">
                <h2 class="col-md-11 col-md-offset-1">Browse.</h2>
                <h2 class="col-md-10 col-md-offset-2">create.</h2>
                <h2 class="col-md-9 col-md-offset-3">share.</h2>
        </div>
    </div>
</div>

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

You are not able to return 'multiple values' in PHP. You can return a single value, which might be an array.

function foo($test1, $test2, $test3)
{
    return array($test1, $test2, $test3);
}
$test1 = "1";
$test2 = "2";
$test3 = "3";

$arr = foo($test1, $test2, $test3);

$test1 = $arr[0];
$test2 = $arr[1];
$test3 = $arr[2];

To fix this solution i followed: this

1.Click Start and then type Run

2.Type services.msc and click OK

3.Scroll down the list and locate that the VMware Authorization service.

4.Click Start the service, unless the service is showing a status of Started.

Add this line in your styles.xml file:

<style>
    <item name="android:colorAccent">@android:color/holo_green_dark</item>
</style>

in fact there exists one trick:

create view view_test as

select
  * 
from 
  table 
where id = (select convert(int, convert(binary(4), context_info)) from master.dbo.sysprocesses
where
spid = @@spid)

... in sql-query:

set context_info 2
select * from view_test

will be the same with

select * from table where id = 2

but using udf is more acceptable

If you can use JQuery, then using the JQuery :focus selector will do the needful

$(this).is(':focus');

Your question may mean two different things:

1.) Open a web page with a browser.

#include <windows.h>
#include <shellapi.h>
...
ShellExecute(0, 0, L"http://www.google.com", 0, 0 , SW_SHOW );

This should work, it opens the file with the associated program. Should open the browser, which is usually the default web browser.

2.) Get the code of a webpage and you will render it yourself or do some other thing. For this I recommend to read this or/and this.

I hope it's at least a little helpful.

EDIT: Did not notice, what you are asking for UNIX, this only work on Windows.

Hi I've blogged about writing a sudoku solver from scratch in Python and currently writing a whole series about writing a constraint programming solver in Julia (another high level but faster language) You can read the sudoku problem from a file which seems to be easier more handy than a gui or cli way. The general idea it uses is constraint programming. I use the all different / unique constraint but I coded it myself instead of using a constraint programming solver.

If someone is interested:

• The old Python version: https://opensourc.es/blog/sudoku
• The new Julia series: https://opensourc.es/blog/constraint-solver-1

Perhaps you want to do

soup.find("li", { "class" : "test" }).find('a')

Use the matplotlib.arrow() function and set the parameters head_length and head_width to zero to don't get an "arrow-end". The connections between the different points can be simply calculated using vector addition with: A = [1,2], B=[3,4] --> Connection between A and B is B-A = [2,2]. Drawing this vector starting at the tip of A ends at the tip of B.

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import style
style.use('fivethirtyeight')


A = np.array([[10,8],[1,2],[7,5],[3,5],[7,6],[8,7],[9,9],[4,5],[6,5],[6,8]])


fig = plt.figure(figsize=(10,10))
ax0 = fig.add_subplot(212)

ax0.scatter(A[:,0],A[:,1])


ax0.arrow(A[0][0],A[0][1],A[1][0]-A[0][0],A[1][1]-A[0][1],width=0.02,color='red',head_length=0.0,head_width=0.0)
ax0.arrow(A[2][0],A[2][1],A[9][0]-A[2][0],A[9][1]-A[2][1],width=0.02,color='red',head_length=0.0,head_width=0.0)
ax0.arrow(A[4][0],A[4][1],A[6][0]-A[4][0],A[6][1]-A[4][1],width=0.02,color='red',head_length=0.0,head_width=0.0)


plt.show()

For whom it needs it, check firewall port 3306 is open too, if your firewall service is running.

Simples

function time($block) {
    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $sw.Elapsed
}

then can use as

time { .\some_command }

You may want to tweak the output

For those using Windows, I had this issue because :

• after running npm uninstall -g @ angular/cli, the folder AppData\Roaming\npm were still containing a ng file
• this file prevented a complete uninstall of the CLI

I tried then to remove the ng file manually, but for some reasons it was not possible (I did not have the right), even as admin.

The only hack I found was using a 'linux based' command (I used Git bash) as admin and removing this file from command line: cd AppData/Roaming/npm rm ng.cmd

For information: this was with the version 6 of the CLI. There is not problem anymore to remove manually this specific file after the update.

Another approach, which is clean and will keep the document valid, is to concatenate the data you want into another tag e.g. id, then use split to take what you want when you want it.

<html>
<script>
  function demonstrate(){
    var x = document.getElementById("example data").querySelectorAll("input");
    console.log(x);
    for(i=0;i<x.length;i++){
      var line_to_illustrate = x[i].id  + ":" + document.getElementById ( x[i].id ).value;
      //concatenated values
      console.log("this is all together: " + line_to_illustrate); 
      //split values
      var split_line_to_illustrate = line_to_illustrate.split(":");
      for(j=0;j<split_line_to_illustrate.length;j++){
        console.log("item " + j+ " is: " + split_line_to_illustrate[j]);
      }      
    }
  }
</script> 

<body>

<div id="example data">
  <!-- consider the id values representing a 'from-to' relationship -->
  <input id="1:2" type="number" name="quantity" min="0" max="9" value="2">
  <input id="1:4" type="number" name="quantity" min="0" max="9" value="1">
  <input id="3:6" type="number" name="quantity" min="0" max="9" value="5">  
</div>

<input type="button" name="" id="?" value="show me" onclick="demonstrate()"/>

</body>
</html>

public void setUp() throws Exception {

 System.setProperty("webdriver.chrome.driver","Absolute path of Chrome driver");

 driver =new ChromeDriver();
 baseUrl = "URL/";

    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

Adding "-EA Stop" solved this for me.

All of above do not work for me.

What I found was click the Details button.

Then following the Multiple contexts with the same path error running web service in Eclipse using Tomcat

Removed the duplicated line then I got an another error.

The server cannot be started because one or more of the ports are invalid. Open the server editor and correct the invalid ports.

Following Can't start tomcatv9.0 in Eclipse

Then it works.

I find that using Apache Commons IO makes my life much easier.

String source = "This is the source of my input stream";
InputStream in = org.apache.commons.io.IOUtils.toInputStream(source, "UTF-8");

You may find that the library also offer many other shortcuts to commonly done tasks that you may be able to use in your project.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

There are a few ways to do this:

1. Use the "Profile or Debug APK" feature in Android Studio 3.0.

   It allows you to open and explore APKs in Android Studio. Classes are decompiled into smali. Resources are not extracted and things like "Go to Definition", "Find All References" and debugging don't work without the source code (android studio 3.0 canary 9). Some additional smali features might work with smalidea.

   

   

   

2. Use jadx.

   Jadx decompiles the code in a given APK to java source files.

   

3. Use apktool.

   Apktool is a command line tool which extracts resources and decompiles code into smali for a given apk. You can recompile using apktool also. Here's an example of it in action:

   $ apktool d test.apk
   I: Using Apktool 2.2.4 on test.apk
   I: Loading resource table...
   I: Decoding AndroidManifest.xml with resources...
   I: Loading resource table from file: 1.apk
   I: Regular manifest package...
   I: Decoding file-resources...
   I: Decoding values */* XMLs...
   I: Baksmaling classes.dex...
   I: Copying assets and libs...
   I: Copying unknown files...
   I: Copying original files...
   $ apktool b test
   I: Using Apktool 2.2.4 on test
   I: Checking whether sources has changed...
   I: Smaling smali folder into classes.dex...
   I: Checking whether resources has changed...
   I: Building resources...
   I: Building apk file...
   I: Copying unknown files/dir...
   

Glide V4:

    Glide.with(context)
        .load(url)
        .circleCrop()
        .into(imageView);

Glide V3:

You can use RoundedBitmapDrawable for circular images with Glide. No custom ImageView is required.

 Glide.with(context).load(url).asBitmap().centerCrop().into(new BitmapImageViewTarget(imageView) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable =
                    RoundedBitmapDrawableFactory.create(context.getResources(), resource);
            circularBitmapDrawable.setCircular(true);
            imageView.setImageDrawable(circularBitmapDrawable);
        }
    });

You can pass a function to the onScroll event on the React element: https://facebook.github.io/react/docs/events.html#ui-events

<ScrollableComponent
 onScroll={this.handleScroll}
/>

Another answer that is similar: https://stackoverflow.com/a/36207913/1255973

http://docs.jquery.com/UI/API/1.8/Dialog

Example for fixed dialog on the left top corner:

$("#dialogId").dialog({
    autoOpen: false,
    modal: false,
    draggable: false,
    height: "auto",
    width: "auto",
    resizable: false,
    position: [0,28],
    create: function (event) { $(event.target).parent().css('position', 'fixed');},
    open: function() {
        //$('#object').load...
    }
});

$("#dialogOpener").click(function() {
    $("#dialogId").dialog("open");
});

I am surprised that the connection string works for you, because it is missing a semi-colon. Set is only used with objects, so you would not say Set strNaam.

Set cn = CreateObject("ADODB.Connection")
With cn
 .Provider = "Microsoft.Jet.OLEDB.4.0"
  .ConnectionString = "Data Source=D:\test.xls " & _
  ";Extended Properties=""Excel 8.0;HDR=Yes;"""
.Open
End With
strQuery = "SELECT * FROM [Sheet1$E36:E38]"
Set rs = cn.Execute(strQuery)
Do While Not rs.EOF
  For i = 0 To rs.Fields.Count - 1
    Debug.Print rs.Fields(i).Name, rs.Fields(i).Value
    strNaam = rs.Fields(0).Value
  Next
  rs.MoveNext
Loop
rs.Close

There are other ways, depending on what you want to do, such as GetString (GetString Method Description).

If you want a Popup that closes automatically, you should look for Toasts. But if you want a dialog that the user has to close first before proceeding, you should look for a Dialog.

For both approaches it is possible to read a text file with the text you want to display. But you could also hardcode the text or use R.String to set the text.

if you want to get text of a selected option (chosen get display selected value)

 $("#select-id").chosen().find("option:selected" ).text();

Do you have a local user.name or user.email that's overriding the global one?

git config --list --global | grep user
  user.name=YOUR NAME
  user.email=YOUR@EMAIL
git config --list --local | grep user
  user.name=YOUR NAME
  user.email=

If so, remove them

git config --unset --local user.name
git config --unset --local user.email

The local settings are per-clone, so you'll have to unset the local user.name and user.email for each of the repos on your machine.

Look at the DefaultTableModel for a simple model that you can use:

http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html

This extends the AbstractTableModel, but should be sufficient for basic purposes. You can always extend AbstractTableModel and create your own. Make sure you set it on the JTable as well.

http://java.sun.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html

Look at the basic Sun tutorial for more information on using the JTable with the table model:

http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data

Objects does not support push property, but you can save it as well using the index as key,

var tempData = {};_x000D_
for ( var index in data ) {_x000D_
  if ( data[index].Status == "Valid" ) { _x000D_
    tempData[index] = data; _x000D_
  } _x000D_
 }_x000D_
data = tempData;

I think this is easier if remove the object if its status is invalid, by doing.

for(var index in data){_x000D_
  if(data[index].Status == "Invalid"){ _x000D_
    delete data[index]; _x000D_
  } _x000D_
}

And finally you don't need to create a var temp –

Just agreeing with ffill method, but one extra info is that you can limit the forward fill with keyword argument limit.

>>> import pandas as pd    
>>> df = pd.DataFrame([[1, 2, 3], [None, None, 6], [None, None, 9]])

>>> df
     0    1   2
0  1.0  2.0   3
1  NaN  NaN   6
2  NaN  NaN   9

>>> df[1].fillna(method='ffill', inplace=True)
>>> df
     0    1    2
0  1.0  2.0    3
1  NaN  2.0    6
2  NaN  2.0    9

Now with limit keyword argument

>>> df[0].fillna(method='ffill', limit=1, inplace=True)

>>> df
     0    1  2
0  1.0  2.0  3
1  1.0  2.0  6
2  NaN  2.0  9

If you need by several params:

$ids = [1,2,3,4];
$not_ids = [5,6,7,8];
DB::table('table')->whereIn('id', $ids)
                  ->whereNotIn('id', $not_ids)
                  ->where('status', 1)
                  ->get();

Although using File.separator to reference a file name is overkill (for those who imagine far off lands, I imagine their JVM implementation would replace a / with a : just like the windows jvm replaces it with a \).

However, sometimes you are getting the file reference, not creating it, and you need to parse it, and to be able to do that, you need to know the separator on the platform. File.separator helps you do that.

You can do like this

SELECT something
FROM
    (a LEFT JOIN b ON a.a_id = b.b_id) LEFT JOIN c on a.a_aid = c.c_id
WHERE a.parent_id = 'rootID'

Make sure your SendTimeout hasn't elapsed after opening the client.

I bet (no language specified) size() method returns length property.

However valid for loop should looks like:

for (int i = 0; i < values.length; i++) {}

I tried every trick but nothing seemed to work and just resulted in hiding the text with the CSS color property to #fff since my background was #fff. Here is the code :

<input class="form-control upload_profile_pic" 
   type="file" 
   name="userfile" class="form-control" 
    style="color: #fff;">

or

input.form-control.upload_profile_pic {
    color: #fff;
}

I use these ways a lot that are very short, and they are like @theunamedguy and @Jim solutions, but with timeout and silent mode in addition.

I especially love the last case and use it in a lot of scripts that run in a loop until the user presses Enter.

  read -rsp $'Press enter to continue...\n'
  

• Escape solution (with -d $'\e')

  read -rsp $'Press escape to continue...\n' -d $'\e'
  

• Any key solution (with -n 1)

  read -rsp $'Press any key to continue...\n' -n 1 key
  # echo $key
  

• Question with preselected choice (with -ei $'Y')

  read -rp $'Are you sure (Y/n) : ' -ei $'Y' key;
  # echo $key
  

• Timeout solution (with -t 5)

  read -rsp $'Press any key or wait 5 seconds to continue...\n' -n 1 -t 5;
  

• Sleep enhanced alias

  read -rst 0.5; timeout=$?
  # echo $timeout
  

Explanation

-r specifies raw mode, which don't allow combined characters like "\" or "^".

-s specifies silent mode, and because we don't need keyboard output.

-p $'prompt' specifies the prompt, which need to be between $' and ' to let spaces and escaped characters. Be careful, you must put between single quotes with dollars symbol to benefit escaped characters, otherwise you can use simple quotes.

-d $'\e' specifies escappe as delimiter charater, so as a final character for current entry, this is possible to put any character but be careful to put a character that the user can type.

-n 1 specifies that it only needs a single character.

-e specifies readline mode.

-i $'Y' specifies Y as initial text in readline mode.

-t 5 specifies a timeout of 5 seconds

key serve in case you need to know the input, in -n1 case, the key that has been pressed.

$? serve to know the exit code of the last program, for read, 142 in case of timeout, 0 correct input. Put $? in a variable as soon as possible if you need to test it after somes commands, because all commands would rewrite $?

It appears that both methods pretty much do the same thing, but the compareTo() method takes in a String, not an Object, and adds some extra functionality on top of the normal equals() method. If all you care about is equality, then the equals() method is the best choice, simply because it makes more sense to the next programmer that takes a look at your code. The time difference between the two different functions shouldn't matter unless you're looping over some huge amount of items. The compareTo() is really useful when you need to know the order of Strings in a collection or when you need to know the difference in length between strings that start with the same sequence of characters.

I was struggling a lot with different solutions including \vspace{-Xmm} on the top and bottom of the page and dealing with warnings and errors. Finally I found this answer:

You can change the margins of just one or more pages and then restore it to its default:

\usepackage{geometry}
...
... 
...
\newgeometry{top=5mm, bottom=10mm}     % use whatever margins you want for left, right, top and bottom.
...
... %<The contents of enlarged page(s)>
...    
\restoregeometry     %so it does not affect the rest of the pages.
...
... 
...

PS:

1- This can also fix the following warning:

LaTeX Warning: Float too large for page by ...pt on input line ...

2- For more detailed answer look at this.

3- I just found that this is more elaboration on Kevin Chen's answer.

You should be able to use jQuery.ajax :

Load a remote page using an HTTP request.

And you can specify which method should be used, with the type option :

The type of request to make ("POST" or "GET"), default is "GET".
Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers.

To get the certificate of remote server you can use openssl tool and you can find it between BEGIN CERTIFICATE and END CERTIFICATE which you need to copy and paste into your certificate file (CRT).

Here is the command demonstrating it:

ex +'/BEGIN CERTIFICATE/,/END CERTIFICATE/p' <(echo | openssl s_client -showcerts -connect example.com:443) -scq > file.crt

To return all certificates from the chain, just add g (global) like:

ex +'g/BEGIN CERTIFICATE/,/END CERTIFICATE/p' <(echo | openssl s_client -showcerts -connect example.com:443) -scq

Then you can simply import your certificate file (file.crt) into your keychain and make it trusted, so Java shouldn't complain.

On OS X you can double-click on the file or drag and drop in your Keychain Access, so it'll appear in login/Certificates. Then double-click on the imported certificated and make it Always Trust for SSL.

On CentOS 5 you can append them into /etc/pki/tls/certs/ca-bundle.crt file (and run: sudo update-ca-trust force-enable), or in CentOS 6 copy them into /etc/pki/ca-trust/source/anchors/ and run sudo update-ca-trust extract.

In Ubuntu, copy them into /usr/local/share/ca-certificates and run sudo update-ca-certificates.

@techedemic is correct but is missing '.' to mention the current directory, and this command go throught all subdirectories.

find . -name '*.gz' -exec gunzip '{}' \;

try this one

$(function () {

 setTimeout(function () {
            if ($(".alert").is(":visible")){
                 //you may add animate.css class for fancy fadeout
                $(".alert").fadeOut("fast");
            }

        }, 3000)

});

depends on your DBMS (people don't seem to know what that is nowadays)

DELETE FROM table LIMIT 1;
-- Postgres:
DELETE FROM table LIMIT 1;
-- MSSql:
DELETE TOP(1) FROM table;

In General to get rid of

Object of class stdClass could not be converted to string.

try to use echo '<pre>'; print_r($sql_query); for my SQL Query got the result as

stdClass Object
(
    [num_rows] => 1
    [row] => Array
        (
            [option_id] => 2
            [type] => select
            [sort_order] => 0
        )

    [rows] => Array
        (
            [0] => Array
                (
                    [option_id] => 2
                    [type] => select
                    [sort_order] => 0
                )

        )

)

In order to acces there are different methods E.g.: num_rows, row, rows

echo $query2->row['option_id'];

Will give the result as 2

One problem with this is that if you forget to (re-)define super for derived classes, then any call to super::something will compile fine but will probably not call the desired function.

For example:

class Base
{
public:  virtual void foo() { ... }
};

class Derived: public Base
{
public:
    typedef Base super;
    virtual void foo()
    {
        super::foo();   // call superclass implementation

        // do other stuff
        ...
    }
};

class DerivedAgain: public Derived
{
public:
    virtual void foo()
    {
        // Call superclass function
        super::foo();    // oops, calls Base::foo() rather than Derived::foo()

        ...
    }
};

(As pointed out by Martin York in the comments to this answer, this problem can be eliminated by making the typedef private rather than public or protected.)

I just found this built into Oracle 10g if that is what you're using. I had to strip all the special characters out for a phone number compare.

regexp_replace(c.phone, '[^0-9]', '')

yourTextView.setText(String.format("Value of a: %.2f", a));

The question is about matplotlib, but for the sake of any R users that end up here given the language-agnostic title:

If you're using an R kernel, just use:

options(repr.plot.width=4, repr.plot.height=3)

The property pDoc.parentElement or pDoc.parentNode will get you the parent element.

I tried all of these options, but my proxy wasn't having any of it for some reason. Then, born out of desparation/despair, I randomly tried curl in my Git Bash shell, and it worked.

Unsetting all of the proxy options using

npm config rm proxy
npm config rm https-proxy

And then running npm install in my Git Bash shell worked perfectly. I don't know how it's set up correctly for the proxy and the Windows cmd prompt isn't, but it worked.

mv in unix-ish systems, move in dos/windows.

e.g.

C:\> move c:\users\you\somefile.txt   c:\temp\newlocation.txt

and

$ mv /home/you/somefile.txt /tmp/newlocation.txt

This is bit out of context but in case you are here because you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

There's no need to do this in two commits, you can add the file and mark it executable in a single commit:

C:\Temp\TestRepo>touch foo.sh

C:\Temp\TestRepo>git add foo.sh

C:\Temp\TestRepo>git ls-files --stage
100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

As you note, after adding, the mode is 0644 (ie, not executable). However, we can mark it as executable before committing:

C:\Temp\TestRepo>git update-index --chmod=+x foo.sh

C:\Temp\TestRepo>git ls-files --stage
100755 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0       foo.sh

And now the file is mode 0755 (executable).

C:\Temp\TestRepo>git commit -m"Executable!"
[master (root-commit) 1f7a57a] Executable!
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100755 foo.sh

And now we have a single commit with a single executable file.

Listen to the change event.

input.onchange = function(e) { 
  ..
};

You can use like this.

when: condition1 == "condition1" or condition2 == "condition2"

All you will have to do is

class BatchCollection(dict):
    def __init__(self, *args, **kwargs):
        dict.__init__(*args, **kwargs)

OR

class BatchCollection(dict):
    def __init__(self, inpt={}):
        super(BatchCollection, self).__init__(inpt)

A sample usage for my personal use

### EXAMPLE
class BatchCollection(dict):
    def __init__(self, inpt={}):
        dict.__init__(*args, **kwargs)

    def __setitem__(self, key, item):
        if (isinstance(key, tuple) and len(key) == 2
                and isinstance(item, collections.Iterable)):
            # self.__dict__[key] = item
            super(BatchCollection, self).__setitem__(key, item)
        else:
            raise Exception(
                "Valid key should be a tuple (database_name, table_name) "
                "and value should be iterable")

Note: tested only in python3

There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....

{
     "name":"myname"
}

And you want to bring in this new json content (adding key "id")

{
     "id": "134",
     "name": "myname"
 }

My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).

import json 

# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' #  assuming same directory (but you can work your magic here with os.)

# read existing json to memory. you do this to preserve whatever existing data. 
with open(PATH_TO_JSON,'r') as jsonfile:
    json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'

Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.

So what we can do now, is simply write to the same filename with the new data

# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"

with open(PATH_TO_JSON,'w') as jsonfile:
    json.dump(json_content, jsonfile, indent=4) # you decide the indentation level

And there you go! data.json should be good to go for an good old POST request

This won't be secure, and it's simple to explain why:

If you hash the password on the client side and use that token instead of the password, then an attacker will be unlikely to find out what the password is.

But, the attacker doesn't need to find out what the password is, because your server isn't expecting the password any more - it's expecting the token. And the attacker does know the token because it's being sent over unencrypted HTTP!

Now, it might be possible to hack together some kind of challenge/response form of encryption which means that the same password will produce a different token each request. However, this will require that the password is stored in a decryptable format on the server, something which isn't ideal, but might be a suitable compromise.

And finally, do you really want to require users to have javascript turned on before they can log into your website?

In any case, SSL is neither an expensive or especially difficult to set up solution any more

Essentially equivalent to the xargs answer, but in case you want parallel execution:

parallel -q cp file1 ::: /foo/ /bar/

So, for example, to copy file1 into all subdirectories of current folder (including recursion):

parallel -q cp file1 ::: `find -mindepth 1 -type d`

N.B.: This probably only conveys any noticeable speed gains for very specific use cases, e.g. if each target directory is a distinct disk.

It is also functionally similar to the '-P' argument for xargs.

From the selectors specification:

Attribute values must be CSS identifiers or strings.

Identifiers cannot start with a number. Strings must be quoted.

1 is therefore neither a valid identifier nor a string.

Use "1" (which is a string) instead.

var a = document.querySelector('a[data-a="1"]');

to clarify your question:

From Python Source code to Java source code? (I don't think so)

.. or from Python source code to Java Bytecode? (Jython does this under the hood)

I had this error today and discovered it was an incorrectly-formatted year...

select * from es_timeexpense where parsedate > to_date('12/3/2018', 'MM/dd/yyy')

Notice the year has only three 'y's. It should have 4.

Double-check your format.

Convert timeofday to string to use indexOf

var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;
console.log(typeof(timeofday)) // for testing will log number
function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)
    var pos = time.indexOf('.');
    var hrs = time.substr(1, pos - 1);
    var min = (time.substr(pos, 2)) * 60;

    if (hrs > 11) {
        hrs = (hrs - 12) + ":" + min + " PM";
    } else {
        hrs += ":" + min + " AM";
    }
    return hrs;
}
 // "" for typecasting to string
 document.getElementById("oset").innerHTML = timeD2C(""+timeofday);

Test Here

Solution 2

use toString() to convert to string

document.getElementById("oset").innerHTML = timeD2C(timeofday.toString());

jsfiddle with toString()

you can attach a focus event to select

$('#select_id').focus(function() {
    console.log('Handler for .focus() called.');
});

Builtin types that don't have constructors in the built-in namespace (e.g. functions, generators, methods) are in the types module. You can use types.FunctionType in an isinstance call:

>>> import types
>>> types.FunctionType
<class 'function'>

>>> def f(): pass

>>> isinstance(f, types.FunctionType)
True
>>> isinstance(lambda x : None, types.FunctionType)
True

Note that this uses a very specific notion of "function" that is usually not what you need. For example, it rejects zip (technically a class):

>>> type(zip), isinstance(zip, types.FunctionType)
(<class 'type'>, False)

open (built-in functions have a different type):

>>> type(open), isinstance(open, types.FunctionType)
(<class 'builtin_function_or_method'>, False)

and random.shuffle (technically a method of a hidden random.Random instance):

>>> type(random.shuffle), isinstance(random.shuffle, types.FunctionType)
(<class 'method'>, False)

If you're doing something specific to types.FunctionType instances, like decompiling their bytecode or inspecting closure variables, use types.FunctionType, but if you just need an object to be callable like a function, use callable.

you may use htmlspecialchars()

<?php
$new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES);
echo $new; // &lt;a href=&#039;test&#039;&gt;Test&lt;/a&gt;
?>

You can also use Ghostscript to merge different PDFs. You can even use it to merge a mix of PDFs, PostScript (PS) and EPS into one single output PDF file:

gs \
  -o merged.pdf \
  -sDEVICE=pdfwrite \
  -dPDFSETTINGS=/prepress \
   input_1.pdf \
   input_2.pdf \
   input_3.eps \
   input_4.ps \
   input_5.pdf

However, I agree with other answers: for your use case of merging PDF file types only, pdftk may be the best (and certainly fastest) option.

Update:
If processing time is not the main concern, but if the main concern is file size (or a fine-grained control over certain features of the output file), then the Ghostscript way certainly offers more power to you. To highlight a few of the differences:

• Ghostscript can 'consolidate' the fonts of the input files which leads to a smaller file size of the output. It also can re-sample images, or scale all pages to a different size, or achieve a controlled color conversion from RGB to CMYK (or vice versa) should you need this (but that will require more CLI options than outlined in above command).
• pdftk will just concatenate each file, and will not convert any colors. If each of your 16 input PDFs contains 5 subsetted fonts, the resulting output will contain 80 subsetted fonts. The resulting PDF's size is (nearly exactly) the sum of the input file bytes.

I had the same issue for PHP 7 version of missing mcrypt.

This worked for me.

sudo apt-get update
sudo apt-get install mcrypt php7.0-mcrypt
sudo apt-get upgrade
sudo service apache2 restart (if needed)

This should solve your problem:

td {
    /* <http://www.w3.org/wiki/CSS/Properties/text-align>
     * left, right, center, justify, inherit
     */
    text-align: center;
    /* <http://www.w3.org/wiki/CSS/Properties/vertical-align>
     * baseline, sub, super, top, text-top, middle,
     * bottom, text-bottom, length, or a value in percentage
     */
    vertical-align: top;
}

You can see dangling commits with git log -g.

-g, --walk-reflogs
 Instead of walking the commit ancestry chain, walk reflog entries from
 the most recent one to older ones. 

So you could do this to find a particular string in a commit message that is dangling:

git log -g --grep=search_for_this

Alternatively, if you want to search the changes for a particular string, you could use the pickaxe search option, "-S":

git log -g -Ssearch_for_this
# this also works but may be slower, it only shows text-added results
git grep search_for_this $(git log -g --pretty=format:%h)

Git 1.7.4 will add the -G option, allowing you to pass -G<regexp> to find when a line containing <regexp> was moved, which -S cannot do. -S will only tell you when the total number of lines containing the string changed (i.e. adding/removing the string).

Finally, you could use gitk to visualise the dangling commits with:

gitk --all $(git log -g --pretty=format:%h)

And then use its search features to look for the misplaced file. All these work assuming the missing commit has not "expired" and been garbage collected, which may happen if it is dangling for 30 days and you expire reflogs or run a command that expires them.

for (const field in this.formErrors) {
  if (this.formErrors.hasOwnProperty(field)) {

for (const key in control.errors) {
  if (control.errors.hasOwnProperty(key)) {

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

\n is a line break. /n is not.

use of \n with

1. echo directly to page

Now if you are trying to echo string to the page:

echo  "kings \n garden";

output will be:

kings garden

you won't get garden in new line because PHP is a server-side language, and you are sending output as HTML, you need to create line breaks in HTML. HTML doesn't understand \n. You need to use the nl2br() function for that.

What it does is:

Returns string with <br /> or <br> inserted before all newlines (\r\n, \n\r, \n and \r).

echo  nl2br ("kings \n garden");

Output

kings
garden

Note Make sure you're echoing/printing \n in double quotes, else it will be rendered literally as \n. because php interpreter parse string in single quote with concept of as is

so "\n" not '\n'

2. write to text file

Now if you echo to text file you can use just \n and it will echo to a new line, like:

$myfile = fopen("test.txt", "w+")  ;

$txt = "kings \n garden";
fwrite($myfile, $txt);
fclose($myfile);
 

output will be:

kings
 garden

This will do:

/^(apple|banana)$/

to exclude from captured strings (e.g. $1,$2):

(?:apple|banana)

An easier option may be to log the POST data before it gets to the server. For web applications, I use Burp Proxy and set Firefox to use it as an HTTP/S proxy, and then I can watch (and mangle) data 'on the wire' in real time.

For making API requests without a browser, SoapUI is very useful and may show similar info. I would bet that you could probably configure SoapUI to connect through Burp as well (just a guess though).

There are no Class literals for parameterized types, however there are Type objects that correctly define these types.

See java.lang.reflect.ParameterizedType - http://java.sun.com/j2se/1.5.0/docs/api/java/lang/reflect/ParameterizedType.html

Google's Gson library defines a TypeToken class that allows to simply generate parameterized types and uses it to spec json objects with complex parameterized types in a generic friendly way. In your example you would use:

Type typeOfListOfFoo = new TypeToken<List<Foo>>(){}.getType()

I intended to post links to the TypeToken and Gson classes javadoc but Stack Overflow won't let me post more than one link since I'm a new user, you can easily find them using Google search

You should use :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="25"/>

That should work!!

If you want to create class then :

.size {
width:100px;
height:100px;
}

and then apply it like :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" class="size" alt="25"/>

by creating a class you can use it at multiple places.

If you want to use only at one place then use inline CSS. Also Inline CSS overrides other CSS.

You can't update two tables at once, but you can link an update into an insert using OUTPUT INTO, and you can use this output as a join for the second update:

DECLARE @ids TABLE (id int);
BEGIN TRANSACTION

UPDATE Table1 
SET Table1.LastName = 'DR. XXXXXX'  
OUTPUT INSERTED.id INTO @ids
WHERE Table1.field = '010008';

UPDATE Table2 
SET Table2.WAprrs = 'start,stop' 
FROM Table2 
JOIN @ids i on i.id = Table2.id;

COMMIT;

I changed your example WHERE condition to be some other field than id. If it's id the you don't need this fancy OUTPUT, you can just UPDATE the second table for the same id='010008'.

def import_class(cl):
    d = cl.rfind(".")
    classname = cl[d+1:len(cl)]
    m = __import__(cl[0:d], globals(), locals(), [classname])
    return getattr(m, classname)

Thanks to Andrew. Here's what a did to use this in cakePHP:

1. Download minify-2.1.7
2. Unpack the file and copy min subfolder to cake's Vendor folder

3. Creates MinifyCodeHelper.php in cake's View/Helper like this:

   App::import('Vendor/min/lib/Minify/', 'HTML');
   App::import('Vendor/min/lib/Minify/', 'CommentPreserver');
   App::import('Vendor/min/lib/Minify/CSS/', 'Compressor');
   App::import('Vendor/min/lib/Minify/', 'CSS');
   App::import('Vendor/min/lib/', 'JSMin');
   class MinifyCodeHelper extends Helper {
       public function afterRenderFile($file, $data) {
           if( Configure::read('debug') < 1 ) //works only e production mode
               $data = Minify_HTML::minify($data, array(
                   'cssMinifier' => array('Minify_CSS', 'minify'),
                   'jsMinifier' => array('JSMin', 'minify')
               ));
           return $data;
       }
   }
   

4. Enabled my Helper in AppController

   public $helpers = array ('Html','...','MinifyCode');

5... Voila!

My conclusion: If apache's deflate and headers modules is disabled in your server your gain is 21% less size and 0.35s plus in request to compress (this numbers was in my case).

But if you had enable apache's modules the compressed response has no significant difference (1.3% to me) and the time to compress is the samne (0.3s to me).

So... why did I do that? 'couse my project's doc is all in comments (php, css and js) and my final user dont need to see this ;)

I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation dependency with NSJSONSerialization as Rob's comment with 15 upvotes suggests.

    NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
      [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
    NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
    NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

    NSLog(@"jsonRequest is %@", jsonRequest);

    NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


    NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error

    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];

    NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
    if (connection) {
     receivedData = [[NSMutableData data] retain];
    }

The receivedData is then handled by:

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSDictionary *question = [jsonDict objectForKey:@"question"];

Though I admit that there should be a better way to do that, but this at least avoids iterating and looping through the object and moves it to the C level.

You use:

yourcommand  > /dev/null 2>&1

If it should run in the Background add an &

yourcommand > /dev/null 2>&1 &

>/dev/null 2>&1 means redirect stdout to /dev/null AND stderr to the place where stdout points at that time

If you want stderr to occur on console and only stdout going to /dev/null you can use:

yourcommand 2>&1 > /dev/null

In this case stderr is redirected to stdout (e.g. your console) and afterwards the original stdout is redirected to /dev/null

If the program should not terminate you can use:

nohup yourcommand &

Without any parameter all output lands in nohup.out

What do you want to do with the attribute? Is it an html attribute or something of your own?

Most of the time you can simply address it as a property: want to set a title on an element? element.title = "foo" will do it.

For your own custom JS attributes the DOM is naturally extensible (aka expando=true), the simple upshot of which is that you can do element.myCustomFlag = foo and subsequently read it without issue.

I have myself struggled with this sometimes and I always found that the solution with all those div's within each other was a messy solution. I just messed around with it a bit, and I personally found out that this works and it certainly is one of the simplest ways:

html {
    position: relative;
}

html, body {
    margin: 0;
    padding: 0;
    min-height: 100%;
}

footer {
    position: absolute;
    bottom: 0;
}

What I like about this is that no extra HTML needs to be applied. You can simply add this CSS and then write your HTML as whenever

Omar's third solution as an HTML Helper would be:

public static IHtmlString FormatNewLines(this HtmlHelper helper, string input)
{
    return helper.Raw(helper.Encode(input).Replace("\n", "<br />"));
}

You can use this code:

AppDomain.CurrentDomain.BaseDirectory

&& is new in C++11, and it signifies that the function accepts an RValue-Reference -- that is, a reference to an argument that is about to be destroyed.

The following answer could be helpful for the first part of your question:

Django: How can I call a view function from template?

Pretty late to the party, but I was struck here and got help from a friend. The thing was not to use PowerMock. This works with the latest version of Mockito.

Mockito comes with this org.mockito.internal.util.reflection.FieldSetter.

What it basically does is helps you modify private fields using reflection.

This is how you use it:

@Mock
private Person mockedPerson;
private Test underTest;

// ...

@Test
public void testMethod() {
    FieldSetter.setField(underTest, underTest.getClass().getDeclaredField("person"), mockedPerson);
    // ...
    verify(mockedPerson).someMethod();
}

This way you can pass a mock object and then verify it later.

Here is the reference.

I'm hoping you are having the same problem that I had... my issue was simple: Make a fixed textarea with locked percentages inside the container (I'm new to CSS/JS/HTML, so bear with me, if I don't get the lingo correct) so that no matter the device it's displaying on, the box filling the container (the table cell) takes up the correct amount of space. Here's how I solved it:

<table width=100%>
    <tr class="idbbs">
        B.S.:
    </tr></br>
    <tr>
        <textarea id="bsinpt"></textarea>
    </tr>
</table>

Then CSS Looks like this...

#bsinpt
{
    color: gainsboro;
    float: none;
    background: black;
    text-align: left;
    font-family: "Helvetica", "Tahoma", "Verdana", "Arial Black", sans-serif;
    font-size: 100%;
  position: absolute;
  min-height: 60%;
  min-width: 88%;
  max-height: 60%;
  max-width: 88%;
  resize: none;
    border-top-color: lightsteelblue;
    border-top-width: 1px;
    border-left-color: lightsteelblue;
    border-left-width: 1px;
    border-right-color: lightsteelblue;
    border-right-width: 1px;
    border-bottom-color: lightsteelblue;
    border-bottom-width: 1px;
}

Sorry for the sloppy code block here, but I had to show you what's important and I don't know how to insert quoted CSS code on this website. In any case, to ensure you see what I'm talking about, the important CSS is less indented here...

What I then did (as shown here) is very specifically tweak the percentages until I found the ones that worked perfectly to fit display, no matter what device screen is used.

Granted, I think the "resize: none;" is overkill, but better safe than sorry and now the consumers will not have anyway to resize the box, nor will it matter what device they are viewing it from.

It works great.

I was with the same problem except with a slight difference, the version of PHPMailer 6.0, by the good friend avs099 I know that the new version of PHPMailer since February 2018 does not support the autoload, and had a serious problem to instantiate the libraries with the namespace in MVC, I leave the code for those who need it.

//Controller
    protected function getLibraryWNS($libreria) {
    $rutaLibreria = ROOT . 'libs' . DS . $libreria . '.php';

    if(is_readable($rutaLibreria)){
        require_once $rutaLibreria;
        echo $rutaLibreria . '<br/>';
    }
    else{
        throw new Exception('Error de libreria');
    }
}

//loginController
    public function enviarEmail($email, $nombre, $asunto, $cuerpo){
    //Import the PHPMailer class into the global namespace
            $this->getLibraryWNS('PHPMailer');
            $this->getLibraryWNS('SMTP');
    //Create a new PHPMailer instance
            $mail = new \PHPMailer\PHPMailer\PHPMailer();
    //Tell PHPMailer to use SMTP
            $mail->isSMTP();
    //Enable SMTP debugging
    //      $mail->SMTPDebug = 0;                                       // 0 = off (for production use),  1 = client messages, 2 = client and server messages  Godaddy POR CONFIRMAR
            $mail->SMTPDebug = 1;                                       // debugging: 1 = errors and messages, 2 = messages only
    //Whether to use SMTP authentication
            $mail->SMTPAuth = true;                                     // authentication enabled
    //Set the encryption system to use - ssl (deprecated) or tls

    //Set the hostname of the mail server
            $mail->Host = "smtp.gmail.com";                             //Host Correo Gmail
    //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
            $mail->Port = 465;      //587;

    //Password to use for SMTP authentication
            $mail->Password = 'tucontraseña';
    //Set who the message is to be sent from
            $mail->setFrom('[email protected]','Creador de Páginas Web');
            $mail->Subject = $asunto;
            $mail->Body = $cuerpo;
    //Set who the message is to be sent to
            $mail->addAddress($email, $nombre);
    //Send the message, check for errors
    if(!$mail->Send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
        return false;
    } else {
        echo "Message has been sent";
        return true;
    }

I was also getting the same error then, i realised that the issue was with the .add(R.id.CONTAINERNAME) So basically i had giving the id = CONTAINERNAME in wrong xml .. So the solution is to first check that you have given the id = CONTAINERNAME in the xml where you want the fragment to be displayed .. Also note that I was trying to call the fragment form an activity.. I hope so thing small mistake will solve the issue

Here you'll find your answer:

Using Git how do I find changes between local and remote

For the lazy:

1. Use "git log origin..HEAD"
2. Use "git fetch" followed by "git log HEAD..origin". You can cherry-pick individual commits using the listed commit ids.

The above assumes, of course, that "origin" is the name of your remote tracking branch (which it is if you've used clone with default options).

An old post but perhaps someone will find this useful;

    foreach($placeholders as $k => $v){

I have three answers to this question:

1. It is against user experience UX best practice to use BLOB and CLOB data types in string and retrieving binary data from an SQL database thus it is advised that you use the technique that involves storing the URL for the image( or any Binary file in the database). This URL will help the user application to retrieve and use this binary file.

2. Second the BLOB and CLOB data types are only available to a number of SQL versions thus functions such as LOAD_FILE or the datatypes themselves could miss in some versions.

3. Third DON'T USE BLOB OR CLOB. Store the URL; let the user application access the binary file from a folder in the project directory.

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

To answer your question about why caching is working, even though the web-server didn't include the headers:

• Expires: [a date]
• Cache-Control: max-age=[seconds]

The server kindly asked any intermediate proxies to not cache the contents (i.e. the item should only be cached in a private cache, i.e. only on your own local machine):

• Cache-Control: private

But the server forgot to include any sort of caching hints:

• they forgot to include Expires, so the browser knows to use the cached copy until that date
• they forgot to include Max-Age, so the browser knows how long the cached item is good for
• they forgot to include E-Tag, so the browser can do a conditional request

But they did include a Last-Modified date in the response:

Last-Modified: Tue, 16 Oct 2012 03:13:38 GMT

Because the browser knows the date the file was modified, it can perform a conditional request. It will ask the server for the file, but instruct the server to only send the file if it has been modified since 2012/10/16 3:13:38:

GET / HTTP/1.1
If-Modified-Since: Tue, 16 Oct 2012 03:13:38 GMT

The server receives the request, realizes that the client has the most recent version already. Rather than sending the client 200 OK, followed by the contents of the page, instead it tells you that your cached version is good:

304 Not Modified

Your browser did have to suffer the delay of sending a request to the server, and wait for a response, but it did save having to re-download the static content.

Why Max-Age? Why Expires?

Because Last-Modified sucks.

Not everything on the server has a date associated with it. If I'm building a page on the fly, there is no date associated with it - it's now. But I'm perfectly willing to let the user cache the homepage for 15 seconds:

200 OK
Cache-Control: max-age=15

If the user hammers F5, they'll keep getting the cached version for 15 seconds. If it's a corporate proxy, then all 67198 users hitting the same page in the same 15-second window will all get the same contents - all served from close cache. Performance win for everyone.

The virtue of adding Cache-Control: max-age is that the browser doesn't even have to perform a conditional request.

• if you specified only Last-Modified, the browser has to perform a request If-Modified-Since, and watch for a 304 Not Modified response
• if you specified max-age, the browser won't even have to suffer the network round-trip; the content will come right out of the caches

The difference between "Cache-Control: max-age" and "Expires"

Expires is a legacy equivalent of the modern (c. 1998) Cache-Control: max-age header:

• Expires: you specify a date (yuck)
• max-age: you specify seconds (goodness)

• And if both are specified, then the browser uses max-age:

  200 OK
  Cache-Control: max-age=60
  Expires: 20180403T192837 
  

Any web-site written after 1998 should not use Expires anymore, and instead use max-age.

What is ETag?

ETag is similar to Last-Modified, except that it doesn't have to be a date - it just has to be a something.

If I'm pulling a list of products out of a database, the server can send the last rowversion as an ETag, rather than a date:

200 OK
ETag: "247986"

My ETag can be the SHA1 hash of a static resource (e.g. image, js, css, font), or of the cached rendered page (i.e. this is what the Mozilla MDN wiki does; they hash the final markup):

200 OK
ETag: "33a64df551425fcc55e4d42a148795d9f25f89d4"

And exactly like in the case of a conditional request based on Last-Modified:

GET / HTTP/1.1
If-Modified-Since: Tue, 16 Oct 2012 03:13:38 GMT

304 Not Modified

I can perform a conditional request based on the ETag:

GET / HTTP/1.1
If-None-Match: "33a64df551425fcc55e4d42a148795d9f25f89d4"

304 Not Modified

An ETag is superior to Last-Modified because it works for things besides files, or things that have a notion of date. It just is

The character 0x0C is be invalid in XML 1.0 but would be a valid character in XML 1.1. So unless the xml file specifies the version as 1.1 in the prolog it is simply invalid and you should complain to the producer of this file.

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

Without your seeing your data (you can use the output of dput(head(survey)) to show us) this is a shot in the dark:

survey <- data.frame(date=c("2012/07/26","2012/07/25"),tx_start=c("2012/01/01","2012/01/01"))

survey$date_diff <- as.Date(as.character(survey$date), format="%Y/%m/%d")-
                  as.Date(as.character(survey$tx_start), format="%Y/%m/%d")
survey
       date   tx_start date_diff
1 2012/07/26 2012/01/01  207 days
2 2012/07/25 2012/01/01  206 days

This solution worked for me using \copy.

psql -h <host> -U <user> -d <dbname> -c "\copy <table_name> FROM '<path to csvfile/file.csv>' with (format csv,header true, delimiter ',');"

See the bottom of this answer for updated (2013) solution using Guava.

This is what I ultimately went with. It turned out we already had a utility method for null-safe String comparison, so the simplest solution was to make use of that. (It's a big codebase; easy to miss this kind of thing :)

public int compareTo(Metadata other) {
    int result = StringUtils.compare(this.getName(), other.getName(), true);
    if (result != 0) {
        return result;
    }
    return StringUtils.compare(this.getValue(), other.getValue(), true);
}

This is how the helper is defined (it's overloaded so that you can also define whether nulls come first or last, if you want):

public static int compare(String s1, String s2, boolean ignoreCase) { ... }

So this is essentially the same as Eddie's answer (although I wouldn't call a static helper method a comparator) and that of uzhin too.

Anyway, in general, I would have strongly favoured Patrick's solution, as I think it's a good practice to use established libraries whenever possible. (Know and use the libraries as Josh Bloch says.) But in this case that would not have yielded the cleanest, simplest code.

Edit (2009): Apache Commons Collections version

Actually, here's a way to make the solution based on Apache Commons NullComparator simpler. Combine it with the case-insensitive Comparator provided in String class:

public static final Comparator<String> NULL_SAFE_COMPARATOR 
    = new NullComparator(String.CASE_INSENSITIVE_ORDER);

@Override
public int compareTo(Metadata other) {
    int result = NULL_SAFE_COMPARATOR.compare(this.name, other.name);
    if (result != 0) {
        return result;
    }
    return NULL_SAFE_COMPARATOR.compare(this.value, other.value);
}

Now this is pretty elegant, I think. (Just one small issue remains: the Commons NullComparator doesn't support generics, so there's an unchecked assignment.)

Update (2013): Guava version

Nearly 5 years later, here's how I'd tackle my original question. If coding in Java, I would (of course) be using Guava. (And quite certainly not Apache Commons.)

Put this constant somewhere, e.g. in "StringUtils" class:

public static final Ordering<String> CASE_INSENSITIVE_NULL_SAFE_ORDER =
    Ordering.from(String.CASE_INSENSITIVE_ORDER).nullsLast(); // or nullsFirst()

Then, in public class Metadata implements Comparable<Metadata>:

@Override
public int compareTo(Metadata other) {
    int result = CASE_INSENSITIVE_NULL_SAFE_ORDER.compare(this.name, other.name);
    if (result != 0) {
        return result;
    }
    return CASE_INSENSITIVE_NULL_SAFE_ORDER.compare(this.value, other.value);
}    

Of course, this is nearly identical to the Apache Commons version (both use JDK's CASE_INSENSITIVE_ORDER), the use of nullsLast() being the only Guava-specific thing. This version is preferable simply because Guava is preferable, as a dependency, to Commons Collections. (As everyone agrees.)

If you were wondering about Ordering, note that it implements Comparator. It's pretty handy especially for more complex sorting needs, allowing you for example to chain several Orderings using compound(). Read Ordering Explained for more!

It always a good practice to pass radix with parseInt -

parseInt(string, radix)

For decimal -

parseInt(id.substring(id.length - 1), 10)

If the radix parameter is omitted, JavaScript assumes the following:

• If the string begins with "0x", the radix is 16 (hexadecimal)
• If the string begins with "0", the radix is 8 (octal). This feature is deprecated
• If the string begins with any other value, the radix is 10 (decimal)

why not use the extension_loaded() function?

if you using Xcode Version 11.1 (11A1027) make sure you are not using the app store credential(provisioning profiles) , because in this case build will be installed and no log or debugger will work, it took me hell lot of time to figure it out , updated Xcode has chagned . now build getting installed on the device without any warning.

Most of these answers do not actually answer the original question. I did a bunch of digging and this was the cleanest solution I found. Here is a slightly more thorough version of that answer:

1. Check out your default branch. Usually git checkout master
2. Run git fetch -p && git branch -vv | awk '/: gone]/{print $1}' | xargs git branch -d

Explanation:

Works by pruning your tracking branches then deleting the local ones that show they are "gone" in git branch -vv.

Notes:

If your language is set to something other than English you will need to change gone to the appropriate word. Branches that are local only will not be touched. Branches that have been deleted on remote but were not merged will show a notification but not be deleted on local. If you want to delete those as well change -d to -D.

The good news is if you have installed python3.4, pyvenv is already been installed. So, Just

pyvenv project_dir
source project_dir/bin/activate
python --version   
python 3.4.*

Now in this virtual env, you can use pip to install modules for this project.

Leave this virtual env , just

deactivate

Goto the Src folder of your Android project, and open the Java file.

Change the package OldName.android.widget to newName.android.widget.

It gives you an error like this

The declared package "newName.android.widget" does not match the expected package "OLDName.android.widget.

To fix this problem, select Move filename.Java to Newname.android.widget and delete the old package folder.

Next step: Go to AndroidManifest.xml and change package="OldName.android.widget" to package="newName.android.widget".

You could also mount a local directory into your docker image and source the script in your .bashrc. Don't forget the script has to consist of functions unless you want it to execute on every new shell. (This is outdated see the update notice.)

I'm using this solution to be able to update the script outside of the docker instance. This way I don't have to rerun the image if changes occur, I just open a new shell. (Got rid of reopening a shell - see the update notice)

Here is how you bind your current directory:

docker run -it -v $PWD:/scripts $my_docker_build /bin/bash

Now your current directory is bound to /scripts of your docker instance.

(Outdated) To save your .bashrc changes commit your working image with this command:

docker commit $container_id $my_docker_build

Update

To solve the issue to open up a new shell for every change I now do the following:

In the dockerfile itself I add RUN echo "/scripts/bashrc" > /root/.bashrc". Inside zshrc I export the scripts directory to the path. The scripts directory now contains multiple files instead of one. Now I can directly call all scripts without having open a sub shell on every change.

BTW you can define the history file outside of your container too. This way it's not necessary to commit on a bash change anymore.

Build URL '/search' as string. Like

"/search?fname="+fname"+"&lname="+lname

Actually I didn't use

 `$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})` 

but I'm sure "params" should be JSON.stringify like for POST

var jsonData = JSON.stringify(
    {
        fname: fname,
        lname: lname 
    }
);

After:

$http({
  method:'GET',
  url:'/search',
  params: jsonData
});

adjustResize = resize the page content

adjustPan = move page content without resizing page content

try this,

EditText editText=(EditText)findViewById(R.id.editText1);

editText.setKeyListener(null);

It works fine...

If you need to treat empty columns as NULLs, try this:

SELECT CAST(nullif(<column>, '') AS integer);

On the other hand, if you do have NULL values that you need to avoid, try:

SELECT CAST(coalesce(<column>, '0') AS integer);

I do agree, error message would help a lot.

maybe if you want array value to be your object key too

function toObject(arr) {
  var rv = {};
  for (var i = 0; i < arr.length; ++i)
    rv[arr[i]] = arr[i];
  return rv;
}

The accepted answer of this question has some issue with chrome when the window is zoomed in to a value >100%. Here is the code recommended by chrome developers as part of a bug i had raised on the same.

$(window).scroll(function() {
  if($(window).scrollTop() + $(window).height() >= $(document).height()){
     //Your code here
  }
});

Chrome Bug

Sending headers earlier than the normal course may have far reaching consequences. Below are just a few of them that happened to come to my mind at the moment:

1. While current PHP releases may have output buffering on, the actual production servers you will be deploying your code on are far more important than any development or testing machines. And they do not always tend to follow latest PHP trends immediately.

2. You may have headaches over inexplicable functionality loss. Say, you are implementing some kind payment gateway, and redirect user to a specific URL after successful confirmation by the payment processor. If some kind of PHP error, even a warning, or an excess line ending happens, the payment may remain unprocessed and the user may still seem unbilled. This is also one of the reasons why needless redirection is evil and if redirection is to be used, it must be used with caution.

3. You may get "Page loading canceled" type of errors in Internet Explorer, even in the most recent versions. This is because an AJAX response/json include contains something that it shouldn't contain, because of the excess line endings in some PHP files, just as I've encountered a few days ago.

4. If you have some file downloads in your app, they can break too, because of this. And you may not notice it, even after years, since the specific breaking habit of a download depends on the server, the browser, the type and content of the file (and possibly some other factors I don't want to bore you with).

5. Finally, many PHP frameworks including Symfony, Zend and Laravel (there is no mention of this in the coding guidelines but it follows the suit) and the PSR-2 standard (item 2.2) require omission of the closing tag. PHP manual itself (1,2), Wordpress, Drupal and many other PHP software I guess, advise to do so. If you simply make a habit of following the standard (and setup PHP-CS-Fixer for your code) you can forget the issue. Otherwise you will always need to keep the issue in your mind.

Bonus: a few gotchas (actually currently one) related to these 2 characters:

1. Even some well-known libraries may contain excess line endings after ?>. An example is Smarty, even the most recent versions of both 2.* and 3.* branch have this. So, as always, watch for third party code. Bonus in bonus: A regex for deleting needless PHP endings: replace (\s*\?>\s*)$ with empty text in all files that contain PHP code.

Sub Results2()

    Dim rCell As Range
    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim lCnt As Long

    Set shSource = ThisWorkbook.Sheets("Sheet1")
    Set shDest = ThisWorkbook.Sheets("Sheet2")

    For Each rCell In shSource.Range("A1", shSource.Cells(shSource.Rows.Count, 1).End(xlUp)).Cells
        lCnt = lCnt + 1
        shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
    Next rCell

End Sub

This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.

To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.

I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,

Sub Results3()

    Dim i As Long, lCnt As Long
    Dim sh As Worksheet

    lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
    Set sh = ThisWorkbook.Sheets("Sheet2")

    Const sSOURCE As String = "Sheet1!"

    For i = 1 To lCnt
        sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
    Next i

End Sub

The easiest way is through keyword arguments:

class City():
  def __init__(self, city=None):
    pass

someCity = City(city="Berlin")

This is pretty basic stuff. Maybe look at the Python documentation?

You can definetely build your code from Vim, that's what the :make command does.

However, you need to go through the basics first : type vimtutor in your terminal and follow the instructions to the end.

After you have completed it a few times, open an existing (non-important) text file and try out all the things you learned from vimtutor: entering/leaving insert mode, undoing changes, quitting/saving, yanking/putting, moving and so on.

For a while you won't be productive at all with Vim and will probably be tempted to go back to your previous IDE/editor. Do that, but keep up with Vim a little bit every day. You'll probably be stopped by very weird and unexpected things but it will happen less and less.

In a few months you'll find yourself hitting o, v and i all the time in every textfield everywhere.

Edit: As of February, 2020, there's now a first-class UI for automatically mounting Drive.

First, open the file browser on the left hand side. It will show a 'Mount Drive' button. Once clicked, you'll see a permissions prompt to mount Drive, and afterwards your Drive files will be present with no setup when you return to the notebook. The completed flow looks like so:

The original answer follows, below. (This will also still work for shared notebooks.)

You can mount your Google Drive files by running the following code snippet:

from google.colab import drive
drive.mount('/content/drive')

Then, you can interact with your Drive files in the file browser side panel or using command-line utilities.

Here's an example notebook

I think this is a nice balance of conciseness, clarity and ease of modification.

characters = ('a'..'z').to_a + ('A'..'Z').to_a
# Prior to 1.9, use .choice, not .sample
(0..8).map{characters.sample}.join

Easily modified

For example, including digits:

characters = ('a'..'z').to_a + ('A'..'Z').to_a + (0..9).to_a

Uppercase hexadecimal:

characters = ('A'..'F').to_a + (0..9).to_a

For a truly impressive array of characters:

characters = (32..126).to_a.pack('U*').chars.to_a

I think you want:

items.GroupBy(item => item.Order.Customer)
     .Select(group => new { Customer = group.Key, Items = group.ToList() })
     .ToList() 

If you want to continue use the overload of GroupBy you are currently using, you can do:

items.GroupBy(item => item.Order.Customer, 
              (key, group) =>  new { Customer = key, Items = group.ToList() })
     .ToList() 

...but I personally find that less clear.

The default value for client_max_body_size directive is 1 MiB.

It can be set in http, server and location context — as in the most cases, this directive in a nested block takes precedence over the same directive in the ancestors blocks.

Excerpt from the ngx_http_core_module documentation:

Syntax:   client_max_body_size size;
Default:  client_max_body_size 1m;
Context:  http, server, location

Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

Don't forget to reload configuration by nginx -s reload or service nginx reload commands prepending with sudo (if any).

One caveat, though. Note that np.array(None).size returns 1! This is because a.size is equivalent to np.prod(a.shape), np.array(None).shape is (), and an empty product is 1.

>>> import numpy as np
>>> np.array(None).size
1
>>> np.array(None).shape
()
>>> np.prod(())
1.0

Therefore, I use the following to test if a numpy array has elements:

>>> def elements(array):
    ...     return array.ndim and array.size

>>> elements(np.array(None))
0
>>> elements(np.array([]))
0
>>> elements(np.zeros((2,3,4)))
24

Would these work?

plt.scatter(np.random.randn(100), np.random.randn(100), facecolors='none')

or using plot()

plt.plot(np.random.randn(100), np.random.randn(100), 'o', mfc='none')

Newer Edit: Lots of things have changed since this question was initially posted - there's a lot of really good information in wallacer's revised answer as well as VisioN's excellent breakdown

Edit: Just because this is the accepted answer; wallacer's answer is indeed much better:

return filename.split('.').pop();

My old answer:

return /[^.]+$/.exec(filename);

Should do it.

Edit: In response to PhiLho's comment, use something like:

return (/[.]/.exec(filename)) ? /[^.]+$/.exec(filename) : undefined;

Another option would be to use the jQuery Transit Framework to handle your CSS3 transitions. The transitions/effects perform well on mobile devices and you don't have to add a single line of messy CSS3 transitions in your CSS file in order to do the animation effects.

Here is an example that will transition an element's opacity to 0 when you click on it and will be removed once the transition is complete:

$("#element").click( function () {
    $('#element').transition({ opacity: 0 }, function () { $(this).remove(); });
});

JS Fiddle Demo

To clarify an already posted solution due to questions in the comments

import numpy

array = numpy.array([49, 51, 53, 56])
array = array - 13

will output:

array([36, 38, 40, 43])

To indicate to the browser that the file should be viewed in the browser, the HTTP response should include these headers:

Content-Type: application/pdf
Content-Disposition: inline; filename="filename.pdf"

To have the file downloaded rather than viewed:

Content-Type: application/pdf
Content-Disposition: attachment; filename="filename.pdf"

The quotes around the filename are required if the filename contains special characters such as filename[1].pdf which may otherwise break the browser's ability to handle the response.

How you set the HTTP response headers will depend on your HTTP server (or, if you are generating the PDF response from server-side code: your server-side programming language).

Is Nothing requires an object that has been assigned to the value Nothing. IsNothing() can take any variable that has not been initialized, including of numeric type. This is useful for example when testing if an optional parameter has been passed.

You seem to have misunderstood how character classes definition works in regex.

To match any of the strings 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, or 12, something like this works:

0[1-9]|1[0-2]

References

• regular-expressions.info/Character Classes
  • Numeric Ranges (have many examples on matching strings interpreted as numeric ranges)

Explanation

A character class, by itself, attempts to match one and exactly one character from the input string. [01-12] actually defines [012], a character class that matches one character from the input against any of the 3 characters 0, 1, or 2.

The - range definition goes from 1 to 1, which includes just 1. On the other hand, something like [1-9] includes 1, 2, 3, 4, 5, 6, 7, 8, 9.

Beginners often make the mistakes of defining things like [this|that]. This doesn't "work". This character definition defines [this|a], i.e. it matches one character from the input against any of 6 characters in t, h, i, s, | or a. More than likely (this|that) is what is intended.

References

• regular-expressions.info/Brackets for Grouping and Alternation with the vertical bar

How ranges are defined

So it's obvious now that a pattern like between [24-48] hours doesn't "work". The character class in this case is equivalent to [248].

That is, - in a character class definition doesn't define numeric range in the pattern. Regex engines doesn't really "understand" numbers in the pattern, with the exception of finite repetition syntax (e.g. a{3,5} matches between 3 and 5 a).

Range definition instead uses ASCII/Unicode encoding of the characters to define ranges. The character 0 is encoded in ASCII as decimal 48; 9 is 57. Thus, the character definition [0-9] includes all character whose values are between decimal 48 and 57 in the encoding. Rather sensibly, by design these are the characters 0, 1, ..., 9.

See also

• Wikipedia/ASCII

Another example: A to Z

Let's take a look at another common character class definition [a-zA-Z]

In ASCII:

• A = 65, Z = 90
• a = 97, z = 122

This means that:

• [a-zA-Z] and [A-Za-z] are equivalent
• In most flavors, [a-Z] is likely to be an illegal character range
  • because a (97) is "greater than" than Z (90)
• [A-z] is legal, but also includes these six characters:
  • [ (91), \ (92), ] (93), ^ (94), _ (95), ` (96)

This error come because of your data contain larger then set value.

Just write down the max_allowed_packed=500M or you can calculate that 500*1024k and use that instead of 500M if you want.

Now just restart the MySQL.

Sorry for the late response, I recently had the same problem with PHP and found out that when working with arrays that do not use $key => $value structure, when using the foreach loop you actual copy the value of the position on the loop variable, in this case $image. Try using this code and it will fix your problem.

for ($i=0; $i < count($images[1]); $i++)
{

    if($images[1][$i] == 'http://i27.tinypic.com/29yk345.gif' ||

    $images[1][$i] == 'http://img3.abload.de/img/10nx2340fhco.gif' ||

    $images[1][$i] == 'http://i42.tinypic.com/9pp2456x.gif')

    {

        unset($images[1][$i]);

    }

}

var_dump($images);die();

You could wrap window.setTimeout like this, which I think is similar to what you were suggesting in the question:

var Timer = function(callback, delay) {
    var timerId, start, remaining = delay;

    this.pause = function() {
        window.clearTimeout(timerId);
        remaining -= Date.now() - start;
    };

    this.resume = function() {
        start = Date.now();
        window.clearTimeout(timerId);
        timerId = window.setTimeout(callback, remaining);
    };

    this.resume();
};

var timer = new Timer(function() {
    alert("Done!");
}, 1000);

timer.pause();
// Do some stuff...
timer.resume();

Use std::string and find.

std::string str = "/user/desktop/abc/post/";
bool exists = str.find("/abc/") != std::string::npos;

This class was compiled with a JDK more recent than the one used for execution.

The easiest is to install a more recent JRE on the computer where you execute the program. If you think you installed a recent one, check the JAVA_HOME and PATH environment variables.

Version 49 is java 1.5. That means the class was compiled with (or for) a JDK which is yet old. You probably tried to execute the class with JDK 1.4. You really should use one more recent (1.6 or 1.7, see java version history).

Try

$items = array_values ( $group_membership );

you can try this: 1. ensure you have added: compile 'com.android.support:design:25.3.1' (maybe you also should add compile 'com.android.support.constraint:constraint-layout:1.0.2') 2.

3.click the Infer Constraints, hope it can help you.

The above works,(having an original document with mixed pages of 11' and 16' wide). However auto rotate needs to be off otherwise landscape pages are saved with page white top and bottom, so dont work in full screen view.

Solution is to re open the new PDF in acrobat and crop the first image (carefully to avoid white border), then select page range i.e. all, this then applies to all pages. job done !

If you are having problem regarding calling Web Service in android then You can use below code to call the web service and get response. Make sure that your the web service return the response in Data Table Format..This code will help you if you using data from SQL Server database. If you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement

void callWebService(){ 

private static final String NAMESPACE = "http://tempuri.org/"; // for wsdl it may be package name i.e http://package_name
private static final String URL = "http://localhost/sample/services/MyService?wsdl";
// you can use IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = "urn:" + METHOD_NAME;

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty("parm_name", prm_value);// Parameter for Method
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;// **If your Webservice in .net otherwise remove it**
    envelope.setOutputSoapObject(request);
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);// call the eb service
                                                                                                         // Method
    } catch (Exception e) {
        e.printStackTrace();
    }

    // Next task is to get Response and format that response
    SoapObject obj, obj1, obj2, obj3;
    obj = (SoapObject) envelope.getResponse();
    obj1 = (SoapObject) obj.getProperty("diffgram");
    obj2 = (SoapObject) obj1.getProperty("NewDataSet");

    for (int i = 0; i < obj2.getPropertyCount(); i++) { 
// the method getPropertyCount() and  return the number of rows
            obj3 = (SoapObject) obj2.getProperty(i);
            obj3.getProperty(0).toString();// value of column 1
            obj3.getProperty(1).toString();// value of column 2
            // like that you will get value from each column

If you are using nginx, you would add proxy_set_header X-Real-IP $remote_addr; to the location block for the site. /etc/nginx/sites-available/www.example.com for example. Here is a example server block.

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    location / {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_pass http://127.0.1.1:3080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

After restarting nginx, you will be able to access the ip in your node/express application routes with req.headers['x-real-ip'] || req.connection.remoteAddress;

If you want to use jQuery, there is $.merge()

Example:

a = [1, 2];
b = [3, 4, 5];
$.merge(a,b);

Result: a = [1, 2, 3, 4, 5]

Check this simple method (It is recommended to put This method in your dateUtility

        }

There is also the -f option that will freshen the zip file. It can be used to update ALL files which have been updated since the zip was generated (assuming they are in the same place within the tree structure within the zip file).

If your file is named /myfiles/myzip.zip all you have to do is

zip -f /myfiles/myzip.zip

And my layout page "_layout.cshtml"

@RenderSection("Scripts", required: true)

So, when I navigate to GetEmployeeDetails.cshtml. I get the error that there is no section scripts to be rendered in GetEmployeeDetails.cshtml. If I change the flag in @RenderSection() from required : true to ``required : false`. It means render the scripts defined in the @section scripts of the views if present.Else, do nothing. And the refined approach would be in _layout.cshtml

@if (IsSectionDefined("Scripts"))
    {
        @RenderSection("Scripts", required: true)
    }

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

Problem

[Vue warn]: Property or method "changeSetting" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option. (found in <MainTable>)

The error is occurring because the changeSetting method is being referenced in the MainTable component here:

    "<button @click='changeSetting(index)'> Info </button>" +

However the changeSetting method is not defined in the MainTable component. It is being defined in the root component here:

var app = new Vue({
  el: "#settings",
  data: data,
  methods: {
    changeSetting: function(index) {
      data.settingsSelected = data.settings[index];
    }
  }
});

What needs to be remembered is that properties and methods can only be referenced in the scope where they are defined.

Everything in the parent template is compiled in parent scope; everything in the child template is compiled in child scope.

You can read more about component compilation scope in Vue's documentation.

What can I do about it?

So far there has been a lot of talk about defining things in the correct scope so the fix is just to move the changeSetting definition into the MainTable component?

It seems that simple but here's what I recommend.

You'd probably want your MainTable component to be a dumb/presentational component. (Here is something to read if you don't know what it is but a tl;dr is that the component is just responsible for rendering something – no logic). The smart/container element is responsible for the logic – in the example given in your question the root component would be the smart/container component. With this architecture you can use Vue's parent-child communication methods for the components to interact. You pass down the data for MainTable via props and emit user actions from MainTable to its parent via events. It might look something like this:

Vue.component('main-table', {
  template: "<ul>" +
    "<li v-for='(set, index) in settings'>" +
    "{{index}}) " +
    "{{set.title}}" +
    "<button @click='changeSetting(index)'> Info </button>" +
    "</li>" +
    "</ul>",
  props: ['settings'],
  methods: {
    changeSetting(value) {
      this.$emit('change', value);
    },
  },
});


var app = new Vue({
  el: '#settings',
  template: '<main-table :settings="data.settings" @change="changeSetting"></main-table>',
  data: data,
  methods: {
    changeSetting(value) {
      // Handle changeSetting
    },
  },
}),

The above should be enough to give you a good idea of what to do and kickstart resolving your issue.

MySQL makes a difference between "localhost" and "127.0.0.1".

It might be possible that 'root'@'localhost' is not allowed because there is an entry in the user table that will only allow root login from 127.0.0.1.

This could also explain why some application on your server can connect to the database and some not because there are different ways of connecting to the database. And you currently do not allow it through "localhost".

Thanks, Varun Rathore. It works perfectly!

For those who want graceful collapse from 4 items per row to 2 items per row depending on the screen width:

<ul class="list-group row">
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_1</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_2</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_3</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_4</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_5</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_6</li>
    <li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_7</li>
</ul>

use app.render in scenarios where you need to render a view but not send it to a client via http. html emails springs to mind.

What you are doing is, you are accepting split response in two different variables, and strings.Split() is returning only one response and that is an array of string. you need to store it to single variable and then you can extract the part of string by fetching the index value of an array.

example :

 var hostAndPort string
    hostAndPort = "127.0.0.1:8080"
    sArray := strings.Split(hostAndPort, ":")
    fmt.Println("host : " + sArray[0])
    fmt.Println("port : " + sArray[1])

you should use []

var x = ConfigurationManager.AppSettings["APIKey"];

Using the example of @Hunter, in the new { .. } part, add readonly = true, I think that will work.

I like using a relative date and shortening the branch name like this:

git for-each-ref --sort='-authordate:iso8601' --format=' %(authordate:relative)%09%(refname:short)' refs/heads

Which gives you output:

21 minutes ago  nathan/a_recent_branch
6 hours ago     master
27 hours ago    nathan/some_other_branch
29 hours ago    branch_c
6 days ago      branch_d

I recommend making a Bash file for adding all your favorite aliases and then sharing the script out to your team. Here's an example to add just this one:

#!/bin/sh

git config --global alias.branches "!echo ' ------------------------------------------------------------' && git for-each-ref --sort='-authordate:iso8601' --format=' %(authordate:relative)%09%(refname:short)' refs/heads && echo ' ------------------------------------------------------------'"

Then you can just do this to get a nicely formatted and sorted local branch list:

git branches

Update: Do this if you want coloring:

#!/bin/sh
#
(echo ' ------------------------------------------------------------??' && git for-each-ref --sort='-authordate:iso8601' --format=' %(authordate:relative)%09%(refname:short)' refs/heads && echo ' ------------------------------------------------------------??') | grep --color -E "$(git rev-parse --abbrev-ref HEAD)$|$"

Here is another way, by rotating element with the scrollbar for 180deg, wrapping it's content into another element, and rotating that wrapper for -180deg. Check the snippet below

When you call document.getElementsByName("name"), you will get a Object. Use .item(index) to traverse all items of a Object

HTML:

<input type="checkbox" onclick="for(c in document.getElementsByName('rfile')) document.getElementsByName('rfile').item(c).checked = this.checked">

<input type=?"checkbox" name=?"rfile" value=?"/?cgi-bin/?">?
<input type=?"checkbox" name=?"rfile" value=?"/?includes/?">?
<input type=?"checkbox" name=?"rfile" value=?"/?misc/?">?

Getting Started

Download the Go distribution

Downloads

Click the link above to visit the Go project's downloads page and select the binary distribution that matches your operating system and processor architecture.

Official binary distributions are available for the FreeBSD, Linux, macOS, and Windows operating systems and the 32-bit (386) and 64-bit (amd64) x86 processor architectures.

If a binary distribution is not available for your combination of operating system and architecture you may want to try installing from source or installing gccgo instead of gc.

Installing Go from source

I can highly recommend checking out the Visual Studio plugin ReSharper. It has a QuickFix feature that does the same (and a lot more).

But ReSharper doesn't require the cursor to be located on the actual code that requires a new namespace. Say, you copy/paste some code into the source file, and just a few clicks of Alt + Enter, and all the required usings are included.

Oh, and it also makes sure that the required assembly reference is added to your project. Say for example, you create a new project containing NUnit unit tests. The first class you write, you add the [TestFixture] attribute. If you already have one project in your solution that references the NUnit DLL file, then ReSharper is able to see that the TestFixtureAttribute comes from that DLL file, so it will automatically add that assembly reference to your new project.

And it also adds required namespaces for extension methods. At least the ReSharper version 5 beta does. I'm pretty sure that Visual Studio's built-in resolve function doesn't do that.

On the down side, it's a commercial product, so you have to pay for it. But if you work with software commercially, the gained productivity (the plug in does a lot of other cool stuff) outweighs the price tag.

Yes, I'm a fan ;)

this will be the appropriate solution for asked question:

String lineNumbers = AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER; EditorsUI.getPreferenceStore().setValue(lineNumbers, true);

Do something like:

def some_function():
    return some_other_function()
def some_other_function():
    return 42 

if you were to run some_function() it would then run some_other_function() and returns 42.

EDIT: I originally stated that you shouldn't define a function inside of another but it was pointed out that it is practical to do this sometimes.

For having a trasition effect like a highlighter just to highlight the text and fade off the bg color, we used the following:

This is the equivalent of append and extend using the + operator:

>>> x = [1,2,3]
>>> x
[1, 2, 3]
>>> x = x + [4,5,6] # Extend
>>> x
[1, 2, 3, 4, 5, 6]
>>> x = x + [[7,8]] # Append
>>> x
[1, 2, 3, 4, 5, 6, [7, 8]]

Your two statements are equivalent.

Most people only use LEFT JOIN since it seems more intuitive, and it's universal syntax - I don't think all RDBMS support RIGHT JOIN.

Primitives vs. References

First :-

Primitive types are the basic types of data: byte, short, int, long, float, double, boolean, char. Primitive variables store primitive values. Reference types are any instantiable class as well as arrays: String, Scanner, Random, Die, int[], String[], etc. Reference variables store addresses to locations in memory for where the data is stored.

Second:-

Primitive types store values but Reference type store handles to objects in heap space. Remember, reference variables are not pointers like you might have seen in C and C++, they are just handles to objects, so that you can access them and make some change on object's state.

Queue is JMS managed object used for holding messages waiting for subscribers to consume. When all subscribers consumed the message , message will be removed from queue.

Topic is that all subscribers to a topic receive the same message when the message is published.

Here is another method using .loc to replace inf with nan on a Series:

s.loc[(~np.isfinite(s)) & s.notnull()] = np.nan

So, in response to the original question:

df = pd.DataFrame(np.ones((3, 3)), columns=list('ABC'))

for i in range(3): 
    df.iat[i, i] = np.inf

df
          A         B         C
0       inf  1.000000  1.000000
1  1.000000       inf  1.000000
2  1.000000  1.000000       inf

df.sum()
A    inf
B    inf
C    inf
dtype: float64

df.apply(lambda s: s[np.isfinite(s)].dropna()).sum()
A    2
B    2
C    2
dtype: float64

Java jar files are the same format as zip files - so if you have a zip file utility that would let you modify an archive, you have your foot in the door. Second problem is, if you want to recompile a class or something, you probably will just have to re-build the jar; but a text file or something (xml, for instance) should be easily enough modified.

long timestamp = Long.parseLong(date)
Date expiry = new Date(timestamp * 1000)

Just discovered a handy way to get an index while parsing. My mind was blown.

$handle = fopen("test.csv", "r");
for ($i = 0; $row = fgetcsv($handle ); ++$i) {
    // Do something will $row array
}
fclose($handle);

Why don't you do:

String number = String.valueOf(input);
char[] digits = number.toCharArray();

Use m.toString() or String.valueOf(m). String.valueOf uses toString() but is null safe.

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____
